. cons'reucrion or surtnnves.

Be it known that "I, CARL Gnone GUL- BRAND, a subject of theKing of Norway, residing at Slemdal, near Christiania, Norway, have invented certain new and useful Improvements in the Construction of Buildings; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use thesam'e, reference beinghad to the accompanying drawings, and to letters or figures of 1 reference marked thereon, which form a part of this specification. I

This invention relates to a system of constructing buildings and principally consists in a system, in which wires are used in a peculiar way to form a skeleton and to bind the constructional parts firmly together.

In the following the invention shall be explained, reference being had to the accompanying drawings showing preferable forms of carrying out the invention in its application to the construction of walls, floors and roofs. v l I Figure 1 is a perspective diagrammatic view of a wall at a corner of a building. Fig. 2 is a similar view of a floor and Fig. 3 of a roof.

In these figures the constructions are shown partly in completed state and partly in a state under erection.

In thefigures similar structural parts are designated by corresponding reference numerals.

In Fig. 1 the framingof the walls is formed by posts or uprights 1 made of wood oriron and of various forms. Around these uprights are stretched strong wires 2 in acontinuous way, the same being stretched in a loop around the corner post and from thence to the next post or upright and so on continuously around the whole building, the wires being at last carried back to the said corner post.- 1

As will be seen, there is hereby formed a strong framing ofhorizontal wires on both sides of the wall. 011 the inner side of the wires forming the exterior framing there are placed sheets or platesB of iron or the like, and outside of the wires forming the interior framing is placed a reed covering'l or the like, said plates 3 and covering 4E serving in conjunction with the wires 2 as a mold for the cast body 5 of the wall. At the same time the plates 3 and the exterior wires serve "Specification of Letters Patent.

as a lock and fastening for the exterior coating 6 the interior reed matting 4 andthe interior wires serving likewise as a locking for the interior coating 7 of the building.

It will be evident that it will be necessary to employ props or stage between the posts 1' for keeping them in place during the stretching of the wires, but these props may be removed as the filling up of the room between the posts with the cast body 5 of the wall advances.

The posts or uprights may be provided with vertical grooves 8 in order to establish a firm connection between the cast body 5 of the wall. .In a corresponding manner the floors are constructed (see Fig. 2), strong continuous wires 2 being stretched across the beams or girders 9 passing oneway on the under side of the girders and the opposite way on the upper side of the girders. At the head of each girder are placed iron corner mountingsll forming guides for the outer wires.

The stretchingof the wires may for instance be commenced at the upper corner of the wall girder (the girder to the extreme right in the drawing), across the upper corners of all the girderheads, and continuing diagonally across the outer side of the wall girder to the extreme left to the lowercorner of its opposite head, and from thence across the lower corners/of all girder heads on the opposite side, until on reaching the wall girder'to the extreme right it is carried diagonally upward on its outer side until meeting the other end of the wire at the upper corner of the said girder. In an exactly corresponding way the next corner wire will be stretched, crossing the former wire on the middle of the wall girders. Between these corner wires the other wires 2 are stretched continuously across all the girders passing first on the under side and then passing back on the upper side of the same.

Between the main wires 2 auxiliary trussing wires 12 may be laid in zigzag as shown in the drawings, preferably along the sides of the girders. For further trussing of the framework auxiliary wires 13 may be stretched diagonally from the heads of the girders under the lower main wires let at the middle of the girders, which wires may be laid double. Other trussing wires 15 may be arranged in planes vertical to the girders from the upper side of one girder to the under side of the next one. The double wires 14 and the auxiliary wires 15 may be kept in position by aid of iron mountings 16 on the under sides of the girders.

As in the walls the wire skeleton is filled up with a cast mass 5, over which the actual flooring 17 is cast or laid.- On the under sideof the floor reed coating 18 wire netting or other material on which to place the ceiling coating is fastened to the lower wires 2.

To insure a better connection with the cast body 5 the girders may be grooved or even provided with openings in such a way as to provide connection between the sections of cast material between the girders thus creating an integral cast flooring mass.

The weight of the flooring mass 5 resting on the lower strings of the wires 2, will tend to keep the upper strings of said wires stretched with a comparatively powerful strain, thereby materially increasing the carrying strength of the flooring placed thereon.

The roofs (Fig. 3) are in all material features constructed in the same way as the floors, the wires 2 beingstretched on both sides of the rafters 19. The noses 20 of the tiles 21 are hooked over the uppermost wires 2, and are preferably laid when the cast mass 5 is still plastic, so that the said noses may be pressed into the said mass and in this way kept securely in place.

It will be understood that the invention is not restricted to the constructional features described and shown, but may be executed in many various forms without departing from its fundamental idea,

Claims:

1. In the construction of buildings, the combination of a plurality of structural members, a plurality of wires extending across said members on both sides thereof and forming a layer of wires on each side of said plurality of members, an imperforate sheeting on the inside of one of said layers Copies of this patent may be obtained for of wires, a cast filling body between said sheeting and the other of said layers of wires, and coatings secured to saidlayers of wires.

2. In the construction of. buildings, the combination of a plurality of structural members, a plurality of wires extending across said members on both sides thereof and forming a layer of wires on each side of said plurality of members, imperforate sheetings on the inside of said layers of wires, a cast filling body between said sheetings, and coatings secured to said layers of wires.

3. In the construction of buildings, the combination of a plurality of structural members, a plurality 01 wires extending across said members on both sides there-o1 and held against movement with respect thereto whereby a layer. of wires is formed on each side oi said plurality of structural members, a sheeting on the inside of one of said layers of wires, a cast filling body between the sheeting and the other of said layers of wires, and coatings engaging said layers of wires 'and locked in position thereby. Y

4. In the construction of buildings the combination of a plurality of posts with a plurality of substantially parallel wires stretched continuously across said posts passing successively and between the individual posts and around the same forming on each side of the said plurality of posts a layer of wires, sheetings on the inside of said layers of wires and a cast filling body between said sheetings and coatings fastened to said layers of wires on the outside of said sheetings and said posts.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
